In many senses the object type is a completely abstract type, since it can hold anything, from native integers to class instances.
You can also have explicitly abstract classes (and/or abstract methods). Needs 0.8.1+
<lang Phix>abstract class job
integer id
-- procedure test(); -- (the ; makes it an abstract method)
procedure show()
printf(1,"this is job:%d\n",id)
end procedure
end class
--job j = new({1}) -- compilation error: "abstract class"
class errand extends job
end class
errand e = new({2})
e.show()</lang>
{{out}}
<pre>
this is job:2
